question 8-i-(b)

Hence, in each of the following cases, find the smallest positive angle q which satisfies the
equation

part b please

how to solve half theta?

 

[ahmed t]

when u get the angle as 42.2 take it as a negative so it will be -42.2 and add the 52.2 and times by two
remember -42.2 is in the 4th quadrant where cos is positive so it is correct and will give u the least value

Ugghhh its 11:30 pm here and I only slept 5hrs last night and Math is DRIVING ME CRAAZY!!
Alright, PLEASE PLEASE answer this URGENTLY!

M/J/10 P31 Q9 (ii)
I dont understand why we differentiate the gradient of the normal? Why dont we just equate it to zero, and then find the x-coordinate, isnt that how we usually find the maximum point's coordinate?

 

[ahmed t]

equating the differentiation of y to zero will give u maximum and minimum y

equating the differentiation of the differentiaiton to zero give maximum and minimum diff which is gradient

Can someone please tell me the the year in which the hardest questions came and was hard enough to get an A in that variant, i wanna take a mock test myself ASAP

 

[diwash]

i think for modulus u draw a line from the origin through the center of the circle and the minimum mod is when it first touches the circle (intersects) and max mod is wen it intersect the circle while leaving it
correct me if im wrong

Thanks ....u r absolutely right...i got it....thank u very much...

Haha, you are awesome Zeebu. This should be something involving moduli and manipulation of both variables simultaneously, right?

ALSO, I have answered your question about the stages of plasmolysis on yahoo answers. Not sure you'll be satisfied with it though, lol.

 

[ahmed t]

the graph has no equation
